I would save some more $$$ and buy a good computerized machine. Sew on a few different brands.
Once you sew on one you will notice the difference right away. I would buy a used computerized machine to keep within the budget.
New machines are way over priced. I could never spend that much on a machine and not feel quilty about the money spent on a sewing machine. I have Bernona sewing machines, and love them. I will never own anything else.
Do a lot of research, and sew on as many machines as possible. Good luck.
